What is a vegan diet?
To determine your vitamin D status, schedule a 25 OH D hydroxyvitamin D blood test at your next medical checkup. We can help those in need to build a solid nutritional foundation, and also supply the right information on how to incorporate hemp foods into their everyday lifestyle. I just came across your blog recently, and I have to say it was virtual love at first sight. I have celiac disease. No More Kidney Stones. We recommend choosing several calcium-rich foods in each food group each day. Am J Clin Nutr ;48 3 Suppl:
Some reviews have expressed the opinion that more research is needed to determine what effect the phytoestrogens in soybeans may have on infants. SBIFs provide complete nutrition that adequately supports normal infant growth and development.
Soybeans can be processed to produce a texture and appearance similar to many other foods. For example, soybeans are the primary ingredient in many dairy product substitutes e.
These substitutes are readily available in most supermarkets. Soy milk does not naturally contain significant amounts of digestible calcium. Many manufacturers of soy milk sell calcium-enriched products, as well. Soy is also used in tempeh: Soy products also are used as a low-cost substitute in meat and poultry products. Extension may result in diminished flavor, but fat and cholesterol are reduced.
Vitamin and mineral fortification can be used to make soy products nutritionally equivalent to animal protein; the protein quality is already roughly equivalent. The soybean is used to make a product called soy nut butter which is similar in texture to peanut butter.
Roasted and ground soybeans can be used as a caffeine-free substitute for coffee. After the soybeans are roasted and ground, they look similar to regular coffee beans or can be used as a powder similar to instant coffee, with aroma and flavor of roasted soybeans. Soybeans with black hulls are used in Chinese fermented black beans, douchi , not to be confused with black turtle beans. Soybeans are also used in industrial products, including oils, soap, cosmetics, resins , plastics, inks, crayons, solvents , and clothing.
According to the American Cancer Society , "Studies in humans have not shown harm from eating soy foods. Moderate consumption of soy foods appears safe for both breast cancer survivors and the general population, and may even lower breast cancer risk.
Saponins , a class of natural surfactants soaps , are sterols that are present naturally in a wide variety of plant foods , including vegetables, legumes, and cereals such as oats. Legumes such as soybean and chickpeas are the major source of saponins in the human diet. Sources of non-dietary saponins include alfalfa, sunflower, herbs and barbasco. Glycitein is a phytoestrogen with weak estrogenic activity, comparable to that of the other soy isoflavones.
Isoflavones are polyphenol compounds,  produced primarily by beans and other legumes, including peanuts and chickpeas. Isoflavones are closely related to flavonoids found in other plants, vegetables and flowers. Soybeans contain the isoflavones, genistein and daidzein , which are phytoestrogen compounds  implicated as potentially beneficial factors in cardiovascular diseases  and numerous other conditions.
The dramatic increase in soyfood sales is largely credited to the Food and Drug Administration 's FDA approval of soy as a cholesterol-lowering food, along with other heart and health benefits. A review  concluded that soy protein is correlated with significant decreases in serum cholesterol, LDL bad cholesterol and triglycerides. However, HDL good cholesterol did not increase by a significant amount.
The FDA granted the following health claim for soy: Solae resubmitted their original petition, asking for a more vague health claim, after their original was challenged and highly criticized. Solae also submitted a petition for a health claim that soy can help prevent cancer.
They quickly withdrew the petition for lack of evidence and after more than 1, letters of protest were received. On 18 February , Weston A. Price Foundation submitted a petition for removal of this health claim. In fact, there is evidence suggesting that lower amounts are indeed efficacious. An American Heart Association AHA review of a decade long study of soy protein benefits casts doubt on the FDA allowed "Heart Healthy" claim for soy protein and does not recommend isoflavone supplementation.
The review panel also found that soy isoflavones have not been shown to reduce post-menopausal "hot flashes" and the efficacy and safety of isoflavones to help prevent cancers of the breast, uterus or prostate is in question.
However, AHA concludes that "many soy products should be beneficial to cardiovascular and overall health because of their high content of polyunsaturated fats, fiber, vitamins, and minerals and low content of saturated fat". The AHA did not conduct a formal statistical analysis of the 22 studies upon which they based their estimate of the potency of soy protein.
When such an analysis was conducted, Jenkins et al. Further, when the analysis was limited to the 11 studies that provided evidence that the control and soy diets were matched, soy protein was found to lower LDL by 5. This estimate is in line with the results of other recently published meta-analyses. Soybeans contain a high level of phytic acid , which has many effects including acting as an antioxidant and a chelating agent. The beneficial claims for phytic acid include reducing cancer,  minimizing diabetes,  and reducing inflammation.
Allergy to soy is common, and the food is listed with other foods that commonly cause allergy, such as milk, eggs, peanuts, tree nuts, shellfish. The problem has been reported among younger children, and the diagnosis of soy allergy is often based on symptoms reported by parents and results of skin tests or blood tests for allergy. Only a few reported studies have attempted to confirm allergy to soy by direct challenge with the food under controlled conditions.
To the extent that it does exist, soy allergy may cause cases of urticaria and angioedema , usually within minutes to hours of ingestion. In rare cases, true anaphylaxis may also occur. The reason for the discrepancy is likely that soy proteins, the causative factor in allergy , are far less potent at triggering allergy symptoms than the proteins of peanut and shellfish. However, this is only a factor when soy proteins reach the blood without being digested, in sufficient quantities to reach a threshold to provoke actual symptoms.
Soy can also trigger symptoms via food intolerance , a situation where no allergic mechanism can be proven. One scenario is seen in very young infants who have vomiting and diarrhoea when fed soy-based formula, which resolves when the formula is withdrawn.
Older infants can suffer a more severe disorder with vomiting, diarrhoea that may be bloody, anemia , weight loss and failure to thrive. The most common cause of this unusual disorder is a sensitivity to cow's milk, but soy formulas can also be the trigger. The precise mechanism is unclear and it could be immunologic, although not through the IgE-type antibodies that have the leading role in urticaria and anaphylaxis.
However, it is also self-limiting and will often disappear in the toddler years. Soybeans contain isoflavones called genistein and daidzein , which are one source of phytoestrogens in the human diet. Because most naturally occurring phytoestrogens act as selective estrogen receptor modulators , or SERMs, which do not necessarily act as direct agonists of estrogen receptors, normal consumption of foods that contain these phytoestrogens should not provide sufficient amounts to elicit a physiological response in humans.
Plant lignans associated with high fiber foods such as cereal brans and beans are the principal precursor to mammalian lignans which have an ability to bind to human estrogen sites. Coumestrol , an isoflavone coumarin derivative, is the only coumestan in foods.
This intake is several orders of magnitude greater than those provided by other nutrients. Although considerable research has examined the potential for soy consumption to lower the risk of breast cancer in women, assessment of these studies indicates there is insufficient population evidence to make a conclusion about this relationship as of A high consumption of omega-6 polyunsaturated fatty acids , which are found in most types of vegetable oil including soybean oil, may increase the likelihood that postmenopausal women will develop breast cancer.
A analysis of the literature said: Because of the phytoestrogen content, some studies have suggested that soybean ingestion may influence testosterone levels in men. However, a meta-analysis of 15 placebo controlled studies showed that neither soy foods nor isoflavone supplements alter measures of bioavailable testosterone or estrogen concentrations in men.
Because of mixed results from animal studies and epidemiological studies, a relatively definitive but expensive controlled study of the impacts of soy on cognitive skills was performed; it found no impact. Though there is some evidence that estrogen can help protect and repair the brain after injury in rats,  there is also evidence that phytoestrogens may be harmful for the recovery of rats in other situations  that have sustained brain injury.
Similarly, epidemiological evidence of humans eating soya products is currently divided: A literature review noted that disturbing data on soy's effect on the cognitive function of the elderly existed. The cover article in the Center for Science in the Public Interest 's September newsletter reported that a controlled study at USC prompted by suggestive epidemiological evidence found no impact on cognitive skills of years of soy vs milk protein diet enrichment.
Though raw soy flour is known to be correlated with pancreatic cancer in rats  the cooked flour has not been found carcinogenic. However, the soy isoflavone genistein has been suggested as a chemopreventive agent against pancreatic cancer, by interfering with the chemical pathways that promote the creation and growth of tumors. The Cancer Council of New South Wales , Australia has released a statement saying scientific research suggests that overall the moderate consumption of soy products does not appear to present a risk to women with breast cancer, and there is equivocal evidence that consuming large amounts of soy products may have a protective effect against developing breast and prostate cancer.
However, the Council does not recommend taking soy dietary supplements as there is no evidence they are either effective or safe at preventing or treating cancers. One review noted that soy based foods may inhibit absorption of thyroid hormone medications required for treatment of hypothyroidism. Soybeans and soy products contain significant amounts of purines , a class of organic compounds.
For people who suffer from gout , eating foods containing moderate or high levels of purines may make the condition worse. National Institutes of Health NIH recommends that gout sufferers limit consumption of soy products although also suggesting that soy may have health benefits by reducing the risk for heart disease.

Is it really bad for you? American Association for Cancer Research. Quantitative Rat Model and Nutritional Considerations". Advances in Experimental Medicine and Biology. Pathogenesis, Prevention and Treatment". The chia seed is nutrient-dense and packs a punch of energy-boosting power. Aztec warriors ate chia seeds to give them high energy and endurance. They said just one spoonful of chia could sustain them for 24 hours. Not only that, but recent research has found that the chia seeds benefits are even greater than we realized.
Chia seeds benefits include promoting healthy skin, reducing signs of aging, supporting the heart and digestive system, building stronger bones and muscles, and more. Continue reading for possible side effects, preparation instructions and a complete list of chia seeds benefits and nutrients. The reason chia seeds are so beneficial is due to them being rich in fiber , omega-3 fats, protein, vitamins and minerals. For example, one ounce 28 grams of chia seeds contain about: Being rich in so many key nutrients, research has uncovered that regularly eating chia seeds can improve your health in numerous ways.
Some of the top chia seeds benefits are:. Researchers from Mexico uncovered that chia seeds had a total natural phenolic antioxidants concentration nearly two times higher than previously reported, and the antioxidant activity was shown to stop up to 70 percent of free radical activity. Chia is super-high in fiber, providing nearly 11 grams per ounce.
According to the National Institutes of Health, seeds like flax and chia can be a natural blood sugar balancer due to their high fiber content and healthy fats.
The rich fiber content in chia seeds also helps people feel more full quicker because it absorbs a considerable amount of water and immediately expands in the stomach when eaten. Also when consumed, chia seeds create a gelatin-like substance in the stomach. In a nutshell, according to research out of Massachusetts: Omega-3s work to protect the heart by lowering blood pressure, bad cholesterol and inflammation. Inflammation can put strain on blood vessels and cause heart disease.
So by eating chia seeds, you can boost and protect your heart thanks to the omega-3s — just another example of the amazing chia seeds benefits available. In the study, half of the athletes drank percent Gatorade, while the others consumed half Gatorade and half chia drink.
By adding a serving of chia seeds a day, you can help boost your metabolism and burn belly fat as well. Just one ounce of chia seeds has about 18 percent of the recommended daily amount of calcium. Calcium is fundamental in bone health and helps maintain bone strength and mass. Chia also contains boron, which is another essential nutrient for bone health.
This is another reason this super seed is great to consume for those trying to put on lean muscle, burn fat and balance blood sugar levels. Chia seeds pack a powerful antioxidant punch to help replace some of those nutrients lost when exercising. Because of this, chia seeds can prolong hydration and improve nutrient absorption of electrolytes. This also slows digestion and keeps you feeling fuller longer, reducing sugar cravings.
Leptin is a key hormone that regulates appetite, how your body spends energy and regulates your energy levels. In , the Journal of Molecular Biochemistry found that ALA limited the growth of cancer cells in both breast and cervical cancers. While more research still needs to be done to find out the deeper implications of ALA on other types of cancer, this is a great discovery for women struggling with these increasingly common types of cancer.
Thus, chia seeds are cancer-fighting foods , yet another one of the amazing chia seeds benefits you can get when you consume them. Calcium is the building block of your teeth and necessary for tooth health.
Zinc prevents tartar by keeping plaque from mineralizing onto your teeth and has an antibacterial effect that keeps bad breath germs away. Vitamin A and phosphorus are also important for strong teeth and a healthy mouth.
These tiny seeds pack such a nutritional punch that expectant mothers should also consider incorporating them into their diets. Pregnancy can deplete your body of important nutrients, and eating chia seeds can help replace those lost nutrients while providing a much needed energy boost.
Most people choose to meet their daily requirements by consuming salmon or fish oil supplements. The mercury content in fish tends to make most pregnant women skeptical, so chia is a great alternative.
For such a tiny seed, chia is quite high in omega-3 fatty acids. Typically, nuts and seeds with high fat content have short shelf lives before they turn rancid, but chia seeds are so rich in antioxidants they can be kept in storage for up to four years without deterioration. Pregnancy is very taxing on the body. Chia seeds pack a powerful antioxidant punch to help replace some of those lost nutrients. Chia seeds contain almost five times the amount of calcium as milk. They also contain boron, another critical mineral for bone health.
Iron is essential to develop the red blood cells that transport oxygen through the body. Some evidence also suggests possible anticoagulant, antioxidant and antiviral effects. High blood sugar makes for a risky pregnancy.
When consumed, chia seeds create a gelatin-like substance in the stomach.
